Tightened the valve cover gaskets.Changed oil ifller cap.Oil cap very tight,new and old.Is this a common problem.
What is the life expectancy of the oil cap,PO replaced it 2-3 years ago and it was leaking a bit already.
When I tried to get a new seal from MB,they laugh at me and said they only sell the whole cap at $8.5 Canadian.Not expensive for MB parts,but seems a waste and environmentally unfriendly.
